I currently administer a few domains for clients which run through our EFA server.
I admit to not having great knowledge on the intricacies of SMTP, so am wondering if/how these new requirements sending email to Gmail will affect us?
I'd rather not get to Feb 1st 2024 and have users unable to send emails to the gmail.com domain so need to look into this as urgent priority.

Currently running EFA 4.0.4 with minimal customisation.

Here's a link for setting up ARC viewtopic.php?p=19707

Also recommend that you have SPF/DKIM/DMARC configured for your domain(s).

Thanks Shawn,

Will investigate DKIM/DMARC over the next few days. Do you have any documentation on setting that up?
I managed to get TLS operational by activating LetsEncrypt so that's one part of it done.
SPF is active across all domains already, so that's also good.
I'll have a read about ARC as well and see if we need to implement it for anyone.
